Vibration analysis and the Shock Pulse Method (SPM) are two of the most popular condition monitoring techniques used in Condition-Based Maintenance (CBM) policy, especially for rotating equipment. To illustrate the extent to which advanced CBM techniques (in this case, vibration analysis and SPM) are applicable and cost effective in a manufacturing company, a pilot pro-ject was followed in real time. The pilot project was performed at a large manu-facturing site in Sweden. The purpose of the project was to implement online condition monitoring of five critical gas circulation fans in the hardening pro-cess of the manufacturing company. This paper presents some of the main findings of the online condition monitor-ing of the fans for a period of two years. Consequently, based on the empirical data, the company was able to gain great profit due to preventing production losses by preventing breakdowns of the fans.
